On Computer Implemented Continuous Dual Auction System

ABSTRACT

A computer implemented continuous dual auction system consisting of a computer, server, and a process for creating a real-time, or substantially real-time, online marketplace for the sale of goods and services. The system allows a buyer to define parameters of one or more items that the buyer wishes to purchase and place a bid on all of the items that satisfy those parameters. The system automatically takes any fees to be paid by the buyer and the seller into account for a buyer&#39;s bid and a seller&#39;s offer. The system may be accessed via a web browser or a remote application.

FIELD OF THE INVENTION

The present disclosure generally relates to a computer implementedcontinuous dual auction system. More specifically, the presentdisclosure relates to a computer implemented continuous dual auctionsystem, including a computer, server, database, real-time, orsubstantially real-time, online marketplace website, and process for thecreation of an online marketplace for the selling and buying of goodsand services.

BACKGROUND

In an effort to meet the growing demand of electronic shopping, virtualonline marketplaces have been setup, providing websites to host theseonline marketplaces for the sale and purchase of goods and services. Oneway for companies, as well as individuals, to buy and sell goods andservices through online marketplaces is through the use of onlineauctions. Traditionally, the most common types of online auctions usedare forward auctions, reverse auctions, Dutch auctions, French auctions,Vickrey auctions, and uniform second price auctions.

In forward auctions, buyers submit competing bids for one product andonly one buyer can win once the auction ends. In this type of auction,the price starts low with the bidders increasing their bids at certainintervals and within a predetermined amount. This type of auction favorsthe seller, as the auction tends to raise the price. Remaining biddersmay be annoyed as they walk away with nothing at the end and could havespent their time elsewhere with a better outcome.

In a reverse auction, sellers compete for the buyer's bid. A buyer willpost a bid for a given service or product, and the sellers will competeto win the bid. This type of auction is beneficial to the buyer as thetransaction price is usually lower than the seller would have normallyconsidered. The reverse auction is not a fair auction because the sellercannot base many different bids against each other to create a truemarket. This means that the reverse auction does not create a faircompetition for the said product.

In a Dutch auction, the auctioneer announces a price for a particulargood or service. Usually, the price falls in equal increments until abid is created from the market. These types of auctions tend to leavebuyers second-guessing themselves as if they could have let the pricefall further. The Dutch auction is not a particularly fair market due tonot being able to see and feel the other bids of the marketplace.

In a French auction, all of the buyers' bids and sellers' offers aresubmitted to the auctioneer in confidence. The auctioneer then decideswhere to open the stock based on these confidences to create the fairprice for the particular security. These types of auctions are mainlyused for the opening of a security and do not usually create enoughinterest to keep an auction going. Throughout a trading day interest ina particular security may increase or decrease, appear or disappear.

In a Vickrey auction, buyers submit bids in confidence to theauctioneer. After collection of all bids, the auctioneer notifies thehighest bidder that he has won; however, he only has to pay the secondhighest bid price. This leaves the winning bidder without thoughts thatthey overpaid for the item because someone else was also willing to paythis price. However, this does leave the second highest bidder withremorse as they should have “won,” in the sense that the item is beingsold at the bid the second highest bidder offered, and now must go toanother source to obtain the item. This type of auction allows buyers tobid the “true value” of an item, i.e., the value of an item is worthwhat someone else is willing to pay for it.

In a uniform second price auction, the auction operates similar to aVickrey auction except there are multiple units of an item to be soldrather than one item. All buyers' bids are submitted in confidence withthe amount they are willing to pay as well as the quantity of the itemwanted. Once the auction closes, the buyer with the highest bid gets thequantity he requested. The auctioneer then goes to the next highest bidwherein that buyer gets the amount he requested, and so forth untilthere are no more units. The winning buyers will all pay the price ofthe lowest winning bid.

A continuous double auction (CDA) is much like the NYSE or NASDAQ stockmarket. Most of the world's stock markets today use the CDA mechanism.In the CDA multiple bidders compete for the commodity of multiplesellers as well as multiple sellers competing for multiple bidders. Thiscreates true price discovery and dictates to the market a commodity'strue value. The CDA is continuous because the market will not close uponexecution of an order. As long as there is at least one bidder and/orone seller, the auction remains open. Also, within the CDA allparticipants may see all open orders for that particular commodity. Allbids and offers are broadcast to the market. Upon an execution, only theaffected parties will be removed from the auction as long as they do nothave any quantity left to fill or they may cancel the remainder of theirorder. The CDA features a true price discovery and creates a fair marketvalue of whatever commodity is being traded. An execution will occurwhen a seller lowers their offer to the highest bid or when a bidderraises their bid to the lowest offer. Until then, all bids and offersremain on the books in the order of precedence, typically first byprice, then by time regardless of quantity. The CDA is the fairest ofall auction mechanisms as all bidders and all sellers may view the depthand breadth of the market and never walk away feeling remorse. Onlyoutside influences will fluctuate the effecting transaction inducing thefair market value of a commodity.

There is a need for an auction system adapted for the online marketplacefor the sale and purchase of goods and services where the benefits of atrue supply and demand model can be realized. In other known onlinemarketplaces, it is far more likely that either the seller dictates theprice or the buyer dictates a price. A buyer dictated or seller dictatedprice might be characterized as an unfair marketplace because the true“price” of a good or service may not be discovered. By allowing allbuyers and sellers to compete against one another in a real-time, orsubstantially real-time, online marketplace, a true price may bediscovered and both buyer and seller can be satisfied.

SUMMARY

In one embodiment, a computer implemented continuous dual auction systemmay include a server to house all of the various databases available forthe different types of items being sold and/or offered for sale. Thesystem may also store user account information. The system may alsoinclude a website that allows the interaction between different users inthe sale and purchasing of items and different ways for the selling andbuying of items. The computer implemented continuous dual auction systemmay provide a way for the user to buy and/or sell goods or services in areal-time, or substantially real-time, online marketplace. In anotherembodiment, the computer implemented continuous dual auction system mayalso provide additional security because of its guaranty andauthorization system.

In another embodiment, the computer implemented continuous dual auctionsystem may provide the ability for the users to enter proxy bids andproxy offers that are hidden from the other users of the real-time, orsubstantially real-time, auction market. One aspect of the proxy systemmay be that it allows for a sale or purchase to happen within set priceparameters setup by a user. Another aspect of the proxy system may bethat it allows the user to step away from the market without riskingmissing another's matching bid or offer for a particular item in a givenonline marketplace. The proxy system may allow for the sale or purchaseto happen at a price the user specifies without the user beingconstantly logged in and actively watching the marketplace. One benefitof this proxy system may be that the user can be doing other things andstill maintain an active order in the marketplace. Another benefit maybe that the user is able to transact with another user within their setparameters while away from the marketplace.

In another embodiment, a real-time, or substantially real-time, onlinemarketplace may be provided wherein both the buyer and seller can seeother bids and offers, as well as their own. Both buyers and sellers maybe able to show their bids and offers, respectively, to the marketplacein order to try to entice the counterparty to raise their bid or lowertheir offer. A further embodiment may include the online marketplacebeing continuous, wherein an auction is open as long as there is a bidor offer for a certain good or service. In one embodiment, when a buyerand seller transact, it may be that only that buyer and that seller areremoved from the marketplace as they have fulfilled their sale orpurchase. All other buyers and sellers may remain in the marketplace. Inanother embodiment, a buyer or seller may remain in the marketplace iftheir entire order has not yet been fulfilled. For instance, a buyer maytransact a portion of their order and remain in the marketplace for theremainder of their order while the seller transacts their entire orderand is removed from the marketplace and vice versa.

In another aspect of the computer implemented continuous dual auctionsystem, various real-time, or substantially real-time, onlinemarketplaces may be created within the host website. For example, onedatabase may be for the sale of concert tickets, one database may be forthe sale of goods such as used furniture, electronics, etc., and yetanother database may be for the sale of services such as carpetcleaning, etc. Where certain items, such as an event ticket, may includehundreds of items, such marketplaces and related databases may befurther separated into more specific marketplaces, such as the sectionin which the tickets are located in a particular venue. Because some ofthese items may have a time limit attached to them, for example the saleof event tickets, such marketplaces may have an end time that matches oris near the start time of the event ticket. For example, the continuousdual auction marketplace for the sale of certain theatre tickets mayclose at a certain time that is the same or substantially the same asthe starting time of the theatre performance. In another embodiment, themarketplace auction to a particular event can remain open until aspecified amount of time passes after the event begins, until the eventends, or there are no more buyers within the auction looking to purchasethe event tickets, or there are no more sellers within the auctionlooking to sell tickets, or both there are no more buyers and sellers inthe marketplace, or any other way of closing the auction. Another aspectof the various continuous dual auction system marketplaces may be theability to support the sale and purchase of both paper tickets as wellas electronic tickets to events, like a football game.

In another aspect of the system, bids and offers are funded or backed,respectively, by a system guaranty. In order for a user to post a bid oran offer, for example, the user must enter or have entered valid creditcard information or setup a funded user account. One advantage of theguaranty is to compensate buyers who fail to receive the purchased itemdue to the seller's failure in transferring the correctly purchased itemto the buyer. Another advantage of the guaranty is to compensate sellerswho fail to receive the proceeds from the item sold due to the buyer'sfailure in transferring funds to the seller. Yet another advantage ofthe guaranty is to eliminate buyers from trying to raise the price ofcertain items where the buyer has no intention of actually buying.

In another aspect of the system, the execution of a sale is dependent onthe amounts of the bids and offers rather than on the date or time inwhich the user posts a bid or offer to the various online marketplacesin the system, unless the bid or offer amount is the same, in which casethe bids and offers are prioritized by the date of entry in the system.An advantage of this system is that it allows the users, buyers andsellers, to immediately see the market rate for a given item rather thansearch through various postings based on dates to get an idea of whatthe market is for a certain item.

In another aspect of the system, a buyer may select one or moreparameters of an item the buyer wishes to purchase. The system allowsthe buyer to bid on any item that satisfies the buyer's parameters. Thesystem notifies any seller of an item satisfying the buyer's parametersof the buyer's bid.

In another aspect of the system, the fees associated with using thesystem are automatically deducted from the bids and offers. When a buyerbids on an item, the buyer's bid includes any fees that the buyer has topay. When a seller receives a buyer's bid, the system notifies theseller of the profit the seller would make by deducting any fees thatthe buyer pays from the buyer's bid in addition to any fees the sellerpays for using the system.

In another aspect of the system, a remote application may be used bybuyers and sellers. Instead of accessing the system via a web browser, aremote application may be used to access the system.

The above summary of the various aspects and embodiments is not intendedto describe each embodiment or every implementation of the computerimplemented continuous dual auction system. Rather, the embodiments arechosen and described so that others skilled in the art may appreciateand understand the principles and practices of the computer implementedcontinuous dual auction system.

As illustrated in FIG. 2, once a user accesses the website or otherinterface 200, the user can search for an item to purchase or sell 202,browse for an event 204, log into his account 206, or register for anaccount 208. An item, as used herein, is meant to include any good orservice that a user is interested in selling or buying, including butnot limited to event tickets, such as sporting events or plays,services, such as rug cleaning, and other goods, such as household orlawn maintenance items, and electronics. A user can search the websiteor other interface for specific items or search for a specificmarketplace to determine if the user would like to participate in anauction. A first-time user may decide to first search for an eventbefore registering, or the user may upon entering the site register as anew user and then go searching the various online marketplaces.Similarly, a returning user can decide to log in immediately uponentering the site or search the various marketplaces before logging into post a bid for the purchase of an item or an offer for the sale of anitem. In one embodiment, the system may remember returning users so thatwhen a returning user enters the website or other interface they areautomatically signed in.

As illustrated in FIG. 3, in one embodiment of the system where a userhas chosen to search for a certain item 300, for example a sportingevent, a user can search for the event by the event (or item) name 302,the event location 304, the event date 306, and/or the type of event (oritem) 308 to determine the actual event or marketplace the user isinterested in selling or buying a ticket to or item from. In anotherembodiment, a user can search for an item by various combinations ofinformation as well as by other suitable information for identifying theitem (or event). Once the user has found the item they were looking for310, unless further information is required to determine the correctmarketplace for the item, the user is directed to the real-time, orsubstantially real-time, auction marketplace webpage for the event.

FIG. 28 is an illustration of one embodiment of an initial searchinterface for a user 2800. In one embodiment, the user may be able totype into a dialog box 2802 the type of item the user is looking for andthen click on, for example, a “Search” button 2804 located next to thedialog box 2802. The system may then direct the user to another webpage,open a new webpage, or present the user with another interface, thatlists related items or item topics that the user can then click on, as abutton or link/hyperlink, which may then direct the user to a morespecific topic or the exact item they are looking for. Depending on theitem, certain additional information may be requested from the user bywhich to determine the exact marketplace to direct the user and/or allowthe user to post a bid or offer. In another embodiment, where a user isunsure of the exact item they are interested in or would simply like tobrowse the marketplaces, a user may be able to search for an item by,for example, a broad topic, such as, but not limited to, concerts 2806,sports 2808, electronics 2810, or other goods 2812. This may beaccomplished, for example, by clicking on a button next to the topic,clicking on an icon/button containing the topic, or clicking on thewords as a link/hyperlink. After clicking on the topic, the user may bedirected to another webpage, a dialog box may open, or the user may bepresented with another interface listing more specific topics, events oritems, wherein a user may further click on those more specific buttonsor links and ultimately be directed to a specific online marketplace foran item or items that fit the user's selections. In another embodiment,for example if the item was an event ticket, the user may be asked toprovide additional information, like the section of the venue soughtbefore being directed into the online marketplace for that section. Asdiscussed in more detail below, a user may be able to post multiple bidsor offers in multiple marketplaces. Once the user has accessed themarketplace and has determined that they would like to enter themarketplace, the user then can, and in some embodiments must, either login or register in order to proceed with the posting of an offer or abid.

FIG. 29 is an illustration of one embodiment of an interface showing theresults of a user's search 2900. In one embodiment, after searching for“Miami,” the events/items column 2902 may be populated with a basketballevent 2904, a musical event 2906, a football event 2908, or a televisionseries on CD 2910. In one embodiment for tickets, each event may showthe corresponding time of the event and location of the event. Inanother embodiment for non-tickets, each item may show the condition ofthe item, completeness of the item, location of the item, or othercriteria suited to describe non-ticket items. The user may then chooseto become a buyer or seller for a particular event or item by selectinga “buy” button 2912 or “sell” button 2914, respectively. In oneembodiment for the basketball event 2904, where a user selects eitherthe “buy” button 2912 or “sell” button 2914, the user may be directed toanother webpage, a dialog box may open, or the user may be presentedwith another interface showing a map of the venue. A seller will whoclicks the “sell” button 2914 will be asked to input specific details ofthe ticket. Once the seller enters this information on the screen thenthey will be taken to either the sellers montage or the enter new offerscreen. The system uses this user-generated information (gate, section,row seat number, event name, event location, event date, event time) andmatches it against an already created database of every single seatwithin the venue. When this information is matched with the database,the system automatically takes the user to the correct market (auction)to which that seller owns the item. This helps prevent fraud and otheruser generated mistakes.

FIG. 30 is an illustration of one embodiment of an interface showing avenue categorized by level 3000. In one embodiment, where the userselects “Miami Heat v. New York Knicks” as shown in FIG. 29, the venuemap for Madison Square Garden 3002 may appear. In one embodiment, thevenue may be categorized by lower level 3004, middle level 3006, upperlevel 3008, and floor level 3010. In another embodiment, the currentbest offer 3012 or best bid 3014 for each level may be listed dependingon whether the user selected to “buy” or “sell,” respectively. The usercan then choose the appropriate level he or she wants to inquire furtherabout by selecting the appropriate level via the select level column3016 or clicking on the appropriate level via the venue map 3002. Theuser may be directed to another webpage, a dialog box may open, or theuser may be presented with another interface showing a map of theselected level of the venue.

FIG. 31 is an illustration of one embodiment of an interface showing alevel categorized by section 3100. In one embodiment, where the userselects “upper level” as shown in FIG. 30, the sections in the upperlevel category 3102 may appear. In one embodiment, the level may becategorized by multiple sections 3104. In another embodiment, thecurrent best offer 3106 or best bid 3108 for each section may be listeddepending on whether the user selected to “buy” or “sell,” respectively.The user can then choose the appropriate section he or she wants toinquire further about by selecting the appropriate section via theselect sections column 3110 or clicking on the appropriate section viathe venue map 3102. The user may be directed to another webpage, adialog box may open, or the user may be presented with another interfaceshowing a map of the selected section of the level.

FIG. 32 is an illustration of one embodiment of an interface showing asection categorized by groups of rows 3200. In one embodiment, where theuser selects a section as shown in FIG. 31, the groups of rows in thechosen section 3202 may appear. In another embodiment, where the userselects “upper level” as shown in FIG. 30, the groups of rows in thechosen level 3202 may appear. In one embodiment, the section or levelmay be categorized by multiple groups of rows 3204. In anotherembodiment, the current best offer 3206 or best bid 3208 for each groupof rows may be listed depending on whether the user selected to “buy” or“sell,” respectively. If the user is a buyer, the user can choose toview tickets 3210 in order to view all offers for a particular group ofrows. If the user is a seller, the user can choose to view tickets 3212in order to view all bids for a particular group of rows. The user maybe directed to another webpage, a dialog box may open, or the user maybe presented with another interface showing all tickets.

As illustrated in FIG. 4, in one embodiment of the system where a userhas chosen to register for an account 400, the user can setup an accountprofile 402. The profile 402 can include creating a username 404 andpassword 406. The account profile can also include the user's personalinformation 408, such as address and phone numbers, as well as theuser's payment information 410, such as credit card information.

FIG. 5 is an illustration of one embodiment of a continuous dual auctionsystem's new user login and profile interface 500. As shown, the usercan create a username 502 and password 504, as well as enter or berequired to enter a valid email address 508. To verify the password, theuser may have to re-enter the password 506. The user may also be askedor required to enter certain other personal information such as theuser's title 510, first name 512, middle name or initial 514, last name516, street address 518, city 520, state 522, zip code 524, daytimephone number 526, evening phone number 528, mobile phone number 530, orany combination thereof. A user may enter this information in any numberof ways. For example, a user may directly type the information into therelevant space, there may be a drop down box in which the user canselect from, or any other way in which to enter data into the system orany combination thereof. Instead of a separate webpage, this may be apop-up box or another interface presented to the user.

In one embodiment, a user may then be required to choose to agree with auser license agreement or other use agreement or terms of service 532.There may be a clickable link or button that will allow the user to viewand read the agreement before agreeing to the terms of the agreement. Auser can agree by clicking in a small dialog box that places a checkmarkin the box indicating agreement, or some other way to signify acceptanceof the agreement. If the user declines to accept the terms of the useragreement by either entering no, failing to click in the dialog box, orotherwise signifying non-acceptance of the license agreement, in someembodiments, the user may not be able to continue with use of thesystem. In other embodiments, the failure to agree to the agreement mayonly prevent a user from being able to participate in an auction,wherein the user may be able to search for and view the variousmarketplaces.

In another embodiment, the user profile may include a promotionalpreference, wherein a user may agree to receive information regardingupcoming events and promotions 534. A user may signify acceptance ornon-acceptance of future information by either typing in yes or no,choosing one from a drop down box, or otherwise signifying the same. Inanother embodiment, the user may agree to receive certain emails oralerts relating to certain services a user may be interested inpurchasing or selling when they come into a marketplace.

In another embodiment, the user profile can include specific bid oroffer alerts, wherein a user may be able to indicate whether the userwould like an email notice or other electronic alert, such as a textmessage, to be sent if an offer is within a certain range of a bid, orvice versa. The user may be able to modify this information as well. Anexample of the alert may be a price drop in percentage or dollar amount.

In one embodiment, the profile page may include the ability for the userto input the user's credit card information upon registering. In anotherembodiment, the user may enter the credit card information upon theposting of a bid or an offer in a marketplace. In another embodiment,the user may have the option of using a stored credit card or entering anew credit card for the funding or backing of a certain bid or offer,respectively.

One advantage of requiring credit card information is its potential usein creating a guaranty, wherein a user may be required to provide validcredit card information to fund a bid for the purchase of an item orback an offer to sell an item. For instance, where the user is a sellerof an event ticket and the user fails to forward the ticket to a buyer,the credit card information could be subjected to a withdrawal in anamount to compensate the buyer for the loss of the ticket, as well asany other applicable fees or charges of the auction system due to suchfailure. In one embodiment, the guaranty may be a guaranty of increasedvalue, such as but not limited to a 125% guaranty, a 150% guaranty, a200% guaranty, or any other suitable increased value guaranty or returnto the buyer wherein the buyer receives back an amount greater than whatthey paid/bid when the item purchased fails to be transferred from theseller to the buyer due to, for example but not limited to, the seller'snegligence or fraudulent behavior. In one embodiment, the guaranty maybe less than 125% or more than 200%. In one embodiment, the guaranty maychange based on the type of marketplace. For instance, the guaranty mayincrease with the value of the item being bought/sold within a certainmarketplace, and vice versa.

In another embodiment, the profile page may include an alternativeoption where the user does not have or does not want to use a creditcard to fund or back the bid or offer. For example, the user may be ableto create an account wherein the user may be able to submit funds to theaccount to be used to fund or back the posting of a bid or offer. In oneembodiment, the user may be able to send a check to a system operatorwherein after the check clears the account is credited with the funds.In another embodiment, the user may be able to electronically transferfunds from one account, such as a checking or savings account, to thesystem account to be used in posting a bid or offer. In a furtherembodiment, a user may have a funded account, as well as saved creditcard information, and the ability to be specific by what means the userwould like to fund or back a bid or offer. In another embodiment, a usermay be able to create more than one account. In another embodiment, auser may also be able to use other methods to fund or back a bid oroffer, such as PayPal accounts and the like.

In a further embodiment, the profile page may allow the user to select aspecific account or credit card as a default, wherein the selectedaccount or credit card will be used as the default account upon theposting of any bid or offer until or unless the user or other authorizedperson elects to change this setting in the profile page. Alternativelyor additionally, the user may elect to have the system verify whichaccount or credit card a user would like to use each time the user postsa bid or offer.

In one embodiment, the log in and/or profile page may include one ormore security questions. For example, the user may be asked to pick froma variety of questions and then in a space provided, for example adialog box, input the answer to that particular question. In oneembodiment, the user may need to pick more than one security questionand input the answers to the particular questions picked. An advantageof security questions is to provide additional security through the login and verification process to help ensure the person logging into theaccount is either the actual user or is an authorized user. In oneembodiment, the user may have to answer one, all, or a combination ofdifferent security questions each time the user logs into the system. Inanother embodiment, the system may randomly pick which question orquestions will be asked. Additionally, the security questions canprovide a way for a user, or authorized person, to recover a usernameand/or password. If a user forgets, for instance, their username orpassword, the system through the use of security questions can providethe user with recovery of the username and password. In one embodiment,the system may require that the user create a new password where theuser has forgotten, for instance, the previous password. This canprovide added security in case the user wrote the username and passwordon a piece of paper, which is missing, for example, someone else hastaken it for unauthorized entry into the system.

One embodiment of the profile page may include the ability for a user toreview the user's complete site history, including all or some of thetransactions the user has made within the system. For example, a usermay be able to view any, all, or certain: bids and/or offers;modifications to bids or offers; cancelations of offers and/or bids;modifications in the quantity of a given item's bid or offer; and/orexecuted transactions. One advantage is that if the user does not wantto keep or maintain a separate record or misplaces/loses/damages theseparate record, the user can review their transactional history on thesite by logging into their profile page. In one embodiment, after a userlogs into the system there may be a link or the user may be presentedwith another interface, for example labeled “Transaction History” orother suitable identifier, wherein the user can click on this link toview all or some of the transactions that have taken place. The link mayopen up a dialog box, a new webpage, and/or direct the user to adifferent webpage. In one embodiment, the user may be able to indicatewhat type of transactions they are interested in viewing, the date rangefor such transactions, the type of item, or other filtering information,or any combination thereof. A user may be able to print out or save thisinformation to a different device. In another embodiment, the user maybe able to view other relevant information, such as the money spentwithin the site, the amount of income received from sales, etc.

FIG. 6 is an illustration of one embodiment of a system's credit cardinformation profile page 600. A user can input the type of credit card602, the credit card number 604, the expiration of the credit card 606,the security code for the credit card 608, the first name shown on thecredit card 610, the middle initial or name shown if shown on the card612, the last name shown on the credit card 614, the billing streetaddress 616, country 618, city 620, state 622, zip code 624, phonenumber 626 and/or email address 628. A user may enter this informationin any number of ways. For example, a user may directly type theinformation into the relevant space, there may be a drop down box inwhich the user can select from, or any other way in which to enter datainto the system or any combination thereof.

As illustrated in FIG. 7, in one embodiment of the system where a userhas chosen to log into their account 700, the user can do severalthings. For instance, a user can update any personal information 702,such as their address or phone number, or set email alerts or personalpreferences 704, and/or update payment information 706, such as modify,delete, or add credit card information. A user can also choose to viewall or some of the negotiations 708, view all or some of the transactedorders 710, view and modify any order that has not transacted 712, aswell as confirm that a transacted order was received 714. Additionally,a user can choose to enter a bid 716 for the purchase of a good orservice, or enter an offer 718 for the sale of a good or service.

Seller

FIG. 8 is a diagram of one embodiment of a seller's options 800, wherethe user becomes a seller for the purposes of selling an item—a good orservice—through the online marketplace auction. If the seller is a firsttime user, the seller can register 802 with the system and create anaccount and online profile. If the seller is a returning user, theseller can log in 804 to their account. If a seller is not a returninguser, the seller may be asked to register by creating a username and/orpassword. In one embodiment, the seller can search 806 the variousdatabases or online marketplaces for the appropriate auction in which tosell their good or service. After a seller has registered and/or loggedin and entered a marketplace, a seller can enter an offer 808 for anitem they would like to sell. If a seller has posted an offer and nolonger wants to wait for an automatic execution of a sale, the sellercan sell the item directly to a buyer 810 and/or negotiate directly witha buyer 812 regarding the sale of that item. The seller can also viewall or some of the current orders for this item 814, as well as view agraphical historical chart 816 of all or some of the transactions thathave occurred in this market. An order for an item can be either a bidor an offer. A seller will only be allowed to enter one posted offer peritem they have to sell. A seller can also browse and view all or some ofthe buyers' bids 818, as well as browse all or some of the buyers andsellers in the marketplace 820.

FIG. 9 is an illustration of one embodiment of the continuous dualauction system's seller montage 900. In one embodiment, the seller maybe directed to a real-time, or substantially real-time, online auctiondatabase system webpage that shows a current bids database 902, a mostrecent transactions database 904, a current best bid and offer database906, a current offers database 908, a seller's toolbox 910, and/or agraphical chart 912. In another embodiment, the webpage may also includethe date and/or time the auction will end 914. In a further embodiment,the webpage may include links to additional information, such as news916, charts 918, weather 920, other marketplace auctions that aresimilar to the specific item being sold 922, and/or other marketplaceauctions that are similar to the general item being sold 924. In oneembodiment of the invention, an auction similar to the specific item canbe, for example, in the case of a concert, different sections or seatswithin the same event. In another embodiment, an auction similar to thespecific item can be, for example, in the case of a concert, differentconcert tickets for the same artist. In one embodiment of the invention,an auction similar to the general item can be an item, for example, inthe case of a concert, different concert tickets for different artists.Additional links, buttons, information, or other suitable alternativesmay be added or deleted depending on the type of item being sold, forexample, whether it is a good or service. In one embodiment, where theitem is a service, a link may be included that would describe in detailthe service and what is included or not included, the possibility ofmodifying the service to include more or less of the services, etc.

In one embodiment, the seller's toolbox 910 may provide the seller withvarious options in modifying the seller's offer. One option may allowthe seller to modify the posted offer by a certain dollar amount. In oneembodiment, a posted offer, as used herein, is meant to include thehighest amount a seller desires to sell an item at, which amount isvisible to all others in the marketplace. In another embodiment, aposted offer, as used herein, is meant to include the lowest amount aseller desires to sell an item at, which amount is visible to all othersin the marketplace. A seller may have the option to modify the postedoffer at any time by a certain dollar amount by clicking a button, forexample, the “Ask−$20” button 926, wherein the seller's posted offeramount may be automatically modified by the amount specified on thebutton. For example, the button “Ask−$20” may decrease the seller'sposted offer by twenty dollars ($20). In one embodiment of the system,offers can be modified by whole dollar amounts eliminating or reducingworthless offer modifications. In one embodiment, the offer can bemodified within certain dollar amount increments, which incrementalamounts may be different based on the item and/or price of the itembeing auctioned. Another advantage of the automatic amount modificationmay be to prevent untrue offers. In one definition of an untrue offer,the seller enters an offer into the system and ends up not sending theitem to the buyer after a transaction either because the seller (1)never had an intention to sell the item when the offer was placed or (2)developed the intention not to sell the item after the offer was placed.In another definition of an untrue offer, the buyer has an item thebuyer wants to purchase and wants to artificially deflate the perceiveddemand for the item in the current offers database 902/1002. The buyerthen places at least one offer for the item, never intending to actuallysell the item, but rather to fool users into thinking that the marketoffer rate is lower for the item than it actually is.

In another embodiment, an offer can be modified in increments of adollar. In one embodiment, the amount of the increments may be dependenton the value of the item in the marketplace. In one embodiment, an offercan be modified by using the keyboard or other input device inmanipulating the amount of the offer.

In one embodiment, another toolbox 910 option may be to sell an item atthe current market price listed in the real-time, or substantiallyreal-time, auction database 902. A seller wishing to sell before theirposted offer is lifted or otherwise desires to affect a sale quicker maysell at the then-currently highest published bid, creating a marketsale. Lifted, as the term is used herein, is meant to include when abuyer enters the marketplace by posting a bid, or modifying a previousbid so that the buyer's bid equals the seller's posted offer. In oneembodiment, to execute a market sale, the seller may click on a buttonindicating a market sale, for example a “Sell Mkt” button 928 in theseller's toolbox 910. In one embodiment, the quantity field 932 mayexpand and/or may be automatically populated with the quantity oftickets the buyer is willing to purchase at that price. The seller maycomplete the transaction by clicking on a button, for example, on the“Submit” or “Continue” button 934. After the seller clicks on the button934, for example, the system may direct the user to another dialog box,webpage, or present the user with another interface to verify that theseller wishes to proceed with this transaction. This may protect againstthe seller inadvertently affecting a market sale where the selleraccidently clicks on the button 934. This may also provide the sellerwith a chance to review the information including the item(s) beingsold, the price, and the buyer before executing the sale. In oneembodiment, the item(s) purchased may then be removed from thereal-time, or substantially real-time, auction database 902. Theseller's offer and the buyer's bid relating to this sale may be removedfrom the real-time, or substantially real-time, auction database 902. Inanother embodiment, the latest transaction database 904 may then beupdated with the most recent sale. In another embodiment, the chart 912will update as well, wherein the chart is a graphical representation ofthe transaction database.

In one embodiment, another option of the toolbox 910 may be for theseller to be able to modify their offer to become the best offer in themarketplace with a single click, as the case may be. In one embodiment,a seller wishing to modify their offer wherein their offer becomes thenew best offer in the marketplace, the seller may be able to click on abutton, for example a “Best Ask” button 930, which would automaticallymodify the seller's offer making it the best offer in the marketplace.In one embodiment, the seller's offer will be modified by theincremental dollar amount already specified in relation to the specificmarketplace. In another embodiment, the seller may be able to indicateby what incremental dollar amount the seller would like their new offerto be the best offer by. In another embodiment, the seller may be ableto enter into the system the exact price the seller wants to modify hisor her offer to.

In one embodiment, another option available to the seller in theseller's toolbox 910 may be for the seller to modify the amount of theitem, such as the amount of tickets or the multiple of tickets, theseller is selling. In one embodiment, the seller may click on a button,for example a “Quantity” or “Inc. Qty x#” button 932, wherein once theseller clicks on the button a dialog box may open, the seller may bedirected to a new webpage, or the seller may be presented with anotherinterface, wherein the seller can modify the number of items, forexample, tickets being offered for sale. In another embodiment, theseller may also be able to modify the multiple of items, such astickets, the seller is willing to sell.

FIG. 10 is an illustration of another embodiment of the continuous dualauction database system's seller montage 1000. In one embodiment, theseller can be directed to a real-time, or substantially real-time,auction database webpage showing the current offers database 1002, themost recent transactions database 1004, the current best bid and offerdatabase 1006, a current bids database 1008, a seller's toolbox 1010,and/or a graphical chart 1012. In another embodiment, the webpage mayalso include the date and/or time the auction will end 1014. In afurther embodiment, the webpage may include links to additionalinformation, such as news 1016, charts 1018, weather 1020, othermarketplace auctions that are similar to the specific item being sold1022, and/or other marketplace auctions that are similar to the generalitem being sold 1024. In one embodiment of the invention, an auctionsimilar to the specific item can be an item within the same auction; forexample, in the case of a concert, different sections or seats withinthe same event. In another embodiment, an auction similar to thespecific item can be other items related to the same auction; forexample, in the case of a concert, different concert tickets for thesame artist. In one embodiment of the invention, an auction similar tothe general item can be an item not within the same auction; forexample, in the case of a concert, different concert tickets fordifferent artists. Additional links, buttons, information, or othersuitable alternatives may be added or deleted depending on the type ofitem being sold, for example, whether it is a good or service. In oneembodiment, where the item is a service, a link may be included thatwould describe in detail the service and what is included or notincluded, the possibility of modifying the service to include more orless of the services, etc.

In a further embodiment, the current offers database 1002 may providethe seller with additional functionality in modifying their offer. Inone embodiment, the database 1002 may have a column entitled “Multiple”1026, for example, wherein the number of the item being sold is listedin the column. For instance, a seller may be selling an item in which hehas a quantity of 10 and wishes to sell them in pairs or otherincrements, thus alerting buyers as to what as well as how many of anitem is being offered for sale. In another embodiment, there may also bea column entitled “Quantity” (not shown on the figure), wherein theseller can enter the number of items he has and/or wishes to sell. Inanother embodiment, the column would also include a way for the sellerto modify the number of the items being sold by either clicking on adown arrow type of a button, for example, or other way in allowing theseller to easily modify the number of the items being sold.

In one embodiment, the database 1002 may include a column entitled “SellNow” 1028, for example. This column may be a button or link wherein ifthe seller presses or clicks on the “Sell Now” button or link associatedwith the bid the seller is interested in (these may be in the same row),a sale may execute. In one embodiment, after the seller clicks, forexample, on the “Sell Now” button, another webpage, dialog box, or otherinterface may open in which the seller has the chance to review the salebefore completing the transaction. This may also act as a safety toverify the seller wanted to make this sale and did not accidently clickon the button.

In one embodiment of the invention, when the seller clicks “Sell Now”1028, the system will allow the seller to select the bid with multiple1026 the seller wishes to sell. In another embodiment, the buyer may bebidding in a smaller multiple 1026 than the seller wishes to sell; inthis case, the seller has to choose another bid that has the multiple1026 the seller desires. In another embodiment, if the buyer is biddingin a smaller multiple 1026 than the seller wishes to sell, the systemwill allow the seller to select negotiate 1030 and inquire if the buyeris willing to purchase the item in the seller's desired multiple 1026.

In another embodiment, the bids can be sorted by clicking on a “sortbids by” 1034 down arrow type of a button and selecting criterion suchas bid price, quantity, multiple, row ranges, aisle seats only, itemneeded by date, or item color.

In one embodiment, the database 1002 may have a column entitled“Negotiate” 1030, for example. This column may be a button or link wherethe seller presses or clicks on the “Negotiate” button or linkassociated with the bid the seller is interested in (these may be in thesame row) and a negotiation notification and/or alert may be sent to theintended buyer. In one embodiment, after the seller clicks, for example,on the “Negotiate” button, another webpage, dialog box, or otherinterface may open in which the seller may begin negotiations with abuyer for the sale of an item. How a negotiation works or may be done isexplained in more detail below with respect to FIG. 14.

In one embodiment, the seller's montage 1000 may have a button entitled“Enter New Offer” 1032, for example. This button or link may allow theseller to enter a new offer into the database 1002. In one embodiment, anew dialog window may open wherein the seller will be able to input therelevant information in order to post an offer into the marketplace. Inone embodiment, the user may be directed to a new webpage wherein theseller would input the requested information required to post an offerwithin the marketplace.

FIG. 11 is an illustration of one embodiment of a seller's iteminformation profile page 1100. In one embodiment, where a seller mayinitiate the posting of an offer, a dialog box may open, the seller maybe directed to a new webpage, or the seller may be presented withanother interface where the seller may be prompted to enter certaininformation related to the item being sold. For example, if the item wasan event ticket, such information as the event name 1102, date 1104,time 1106, venue 1108, section 1110, row 1112, seats 1114, and/orwhether there is an obstructed view 1116 may be entered into the system.A seller may enter this information in any number of ways. For example,a seller may directly type the information into the relevant spaces,there may be a drop down box from which the seller can selectinformation, or any other way in which to enter data into the system orany combination thereof.

In one embodiment, a link may pull up a map of the venue in which theseller may be able to click within a certain section of the venue mapand these entries will be automatically populated with this information.Depending on the item being sold, a seller may be required to enter someor all of this information, i.e., some of the information may beoptional. What information a seller may enter may be dependent on whatis being sold by the seller, wherein additional or different informationmay be required or optional for the seller to enter.

The seller may also input the proxy offer 1118, the posted offer 1120,the quantity of tickets being sold 1122, and in what multiple 1124 thetickets may be sold if the seller has more than one. The proxy offer1118, as used herein, is meant to include the lowest amount a seller iswilling to sell an item for, which amount is not visible to others inthe marketplace. How a proxy offer 1118 works is explained in moredetail in FIG. 20 below. A seller may enter this information in anynumber of ways. For example, a seller may directly type the informationinto the relevant space, there may be a drop down box in which theseller can select from, or any other way in which to enter data into thesystem or any combination thereof. Instead of a separate webpage, thismay be a pop-up box or other interface presented to the user. The sellermay click a button, for example, a “Continue” button 1126, wherein theseller may choose the means in which the seller would like to back theoffer. For example, the seller may choose to back the offer by using theseller's system account, which may have been funded by the seller's ownfunds, a saved credit card, or enter a new or different credit card toproceed with the posting of the offer in the marketplace auction.

FIG. 12 is an illustration of one embodiment of a dialog box in which aseller may select a credit card to use for a transaction 1200. Theseller may select to use the credit card information already stored inthe seller's account profile, or, if there is more than one credit cardstored, the seller may choose the credit card they would like to use forthe transaction, or the seller may enter credit card information intothe system for the purpose of this transaction. If a seller has multiplecredit cards on file, at the top of the dialog box, for instance in oneembodiment, the seller may be able to choose which credit card theywould like to use, for example, from a drop down box 1202 or othermeans. The seller may be required to enter the security code 1204associated with the chosen credit card and/or the seller's email address1206, for verification purposes. If the seller does not have or does notwant to use a saved or new credit card, the seller may choose to use theseller's system account instead. If the seller has more than oneaccount, the seller may be able select which account the seller wouldlike to use to back the offer being posted.

If the seller would like to use a new and/or different credit card forthe transaction, the seller may input the type of credit card 1208, thecredit card number 1210, the expiration of the credit card 1212, thesecurity code for the credit card 1214, the first name shown on thecredit card 1216, the middle initial or name shown if shown on the card1218, the last name shown on the credit card 1220, the billing streetaddress 1222, country 1224, city 1226, state 1228, zip code 1230, phonenumber 1232 and/or email address 1234. Some information that a sellermay input may be required and some information may be optional. Afterthe seller inputs this information, the seller may click on a button tocontinue, such as a button labeled “Continue” 1236. The seller may beasked by the system if the seller would like to save this credit cardinformation in the system. This may be accomplished in any number ofways, for example in one embodiment a pop-up, dialog box may appearafter a seller clicks the “Continue” button 1236. If the seller wishesto save the credit card, they may be asked to name the card for laterrecognition. If not, in one embodiment or an alternative embodiment, thecredit card information may remain in the system for only the durationof the auction in which the seller has the offer listed, which offerincludes this particular credit card information. For purposes of aseller's offer, in some embodiments, the credit card may not be usedexcept for guaranty purposes. If a seller does not complete a sale bythe time the auction ends, the credit card information may be deletedfrom the system. In another embodiment, the credit card information mayremain in the system as part of the user history.

After the credit card information is entered into the system andconfirmed, or the account is verified to contain sufficient funds, theauction database system may upload the item information being sold intothe related event-specific real-time, or substantially real-time,auction system database and marketplace, as noted above with respect toFIG. 9. The seller may be brought into the online auction marketplaceand may be able to see all other bids and offers relating to thespecific item.

In one embodiment, a seller may have the ability to submit multipleoffers. For instance, if a seller is looking to sell multiple items ortickets to a certain event, where for example the tickets may be forseats that are located in different sections or levels of a particularvenue, the seller may be able to post several offers across differentlevels or sections of a particular venue for a particular event. Wheresome event locations, such as stadiums, theatres, etc., are broken downinto different “areas,” like sections or levels, a seller can post anoffer based on the different areas available for each event. In oneembodiment, after a seller posts an offer in an online marketplace,there may be a button or link, such as “Post Offer,” wherein the sellercan then submit another offer for a different section or level of thevenue. In an alternative embodiment, after a seller posts an offer tothe online marketplace, a dialog box may appear asking whether theseller would like to post another offer. In another embodiment, theseller actually owns the item or ticket before posting an offer for itin the system. In an alternative embodiment, the seller does not own theitem or ticket, but posts an offer for it in the system anyway; inanticipation of the item or ticket selling, the seller then intends topurchase the same item or ticket almost simultaneously from some sourceto fulfill the contract.

FIG. 22 is an illustration of one embodiment of an interface forentering an offer for an item 2200. In one embodiment, at or about thetime when a seller is entering an offer, the seller may be prompted witha dialog box or other interface to indicate whether this particularoffer should be canceled by a certain date 2202. In further embodiments,the seller may be prompted with a dialog box or other interface toindicate whether this particular offer should be canceled upon anotheroffer's execution for: (1) the same event 2204; (2) the same event in aparticular level 2206; (3) the same event in a particular section 2208;(4) the same event in a particular row 2210; (5) the same event before aparticular date 2212; (6) the same event if the price of the otheroffer's execution is higher than a particular price 2214; and/or (7) thesame event if the price of the other offer's execution is lower than aparticular price 2216. If the seller indicates he or she would like theoffer to be canceled upon execution of another offer and one of theother offers is executed, then this offer may be canceled and removedfrom the real-time, or substantially real-time, auction database systemautomatically. If the seller indicates he or she would like the offer toremain active upon another offer's execution and one of the other offersis executed, then this offer may remain active in the real-time, orsubstantially real-time, auction database system, wherein the seller cansell additional items, such as event tickets to a specified event. In afurther embodiment, the seller may be able to post offers in multipledifferent marketplaces, wherein the seller may be able to post multipleoffers within each such marketplace.

FIG. 23 is an illustration of one embodiment of an interface formodifying an offer for an item 2300. In one embodiment, the system mayallow the seller full functionality to cancel and/or modify offers atany time. In another embodiment, at or about the time when a seller isentering modifying an offer, the seller may be prompted with a dialogbox or other interface to indicate whether this particular offer shouldbe canceled by a certain date 2310. In another embodiment, the sellermay modify the quantity 2302, multiple 2304, price 2306, and/or proxyprice 2308 for an offer at any time. In further embodiments, the sellermay modify the offer by indicating that a particular offer should becanceled upon another offer's execution for: (1) the same event 2312;(2) the same event in a particular level 2314; (3) the same event in aparticular section 2316; (4) the same event in a particular row 2318;(5) the same event before a particular date 2320; (6) the same event ifthe price of the other offer's execution is higher than a particularprice 2322; and/or (7) the same event if the price of the other offer'sexecution is lower than a particular price 2324.

FIG. 24 is an illustration of one embodiment of an interface showing allactive offers for seller's items 2400. In another embodiment, the usercan view both their active offers and active bids. In one embodiment, aseller may enter as many offers as a seller wishes; however, as soon asa sale is executed all other remaining offers may be automaticallycanceled from the system for that particular item and/or in thatparticular marketplace. For example, all offers may be canceled uponanother offer's execution for: (1) the same event 2402; (2) the sameevent in a particular level 2404; (3) the same event in a particularsection 2406; (4) the same event in a particular row 2408; (5) the sameevent before a particular date 2410; (6) the same event if the price ofthe other offer's execution is higher than a particular price 2412;and/or (7) the same event if the price of the other offer's execution islower than a particular price 2414. In another embodiment, the sellermay cancel all offers within a certain row or row range 2416, placedbefore a certain date and time 2418, made before another particularoffer 2420, and/or made after another particular offer 2422. In anotherembodiment, the system may allow a seller to keep open remaining offerseven after a sale has been completed, wherein the seller can dictatewhich offers the seller would like to remain active and which offersshould be canceled. In another embodiment of the invention, a seller mayhave multiple offers open but only want two of the offers linked suchthat if one offer executes the other linked offer cancels but theremaining offers stay open 2424. In another embodiment of the invention,a seller may have multiple offers open but only want two or more of theoffers linked such that if one offer executes the other linked offerscancel but the remaining offers stay open. In another embodiment, theactive offers can be sorted via a “view by” box 2426. The seller cansort the active offers by criterion such as order number, item type,event type, quantity, price, levels, sections, rows, whether negotiationis in process, and/or if an offer is linked to another offer forcancellation.

In one embodiment, the input of a seller's credit card information mayfund a guaranty that a seller will complete a sale by transferring orsending the sold item to a buyer. In one embodiment, this may be of theform in which after a sale is completed, the seller's credit card isauthorized an amount greater than or equal to the amount of the saleprice of the item, and optionally any system fees associated with thetransaction. This amount may be placed into an escrow account for aperiod of time, for example, forty-eight (48) hours until confirmationof the item is received. This time may be modified depending on the typeof item being sold, the location of the parties, the mode oftransferring the item, and the type of parties involved. If a sellerdoes default on a sale, the buyer may be credited with an amount that isthe sale price of the item or greater, which sum may be obtained fromthe escrow account, or directly from the seller's credit card.Additionally, for example, the defaulting seller may be banned and/orreported for fraud. In one embodiment of the invention, after atransaction is executed, the buyer is able to use a radio button toindicate if the seller shipped the item to the buyer or defaulted on thesale. In another embodiment, after a transaction is executed, if thebuyer does not receive his or her item, the buyer can contact thewebsite and the website will determine if the seller has defaulted onthe sale. There are many other ways in which the auction system may funda guaranty for the possibility of a defaulting seller.

When a seller is notified of a completed sale, in one embodiment, theseller may also be notified of how the buyer would like to receive theitem. For example, the seller may be able to print a label to ship theitem by mail or otherwise, such as FedEx or UPS, or in the event ofe-tickets, for example, email the item directly to the buyer. There arenumerous ways in which the seller may be notified on how to transfer theitem from the seller to the buyer.

In one embodiment of the system, the seller may provide inventory datato the auction via a programmatic interface. As illustrated in FIG. 34,the auction system 3401 can accept an inventory file 3402 from theseller. The inventory file can contain data including, but not limitedto, the items available for sale by the seller, and posted and proxyoffers for each inventory item or group of inventory items. Theinventory file can be a text file, database file, XML file, spreadsheetfile, or any other known file format. The auction system may be able toupdate the inventory file with the latest status of the inventory itemslisted. The seller may update the inventory file 3403 via an editorappropriate for the file format, for example, a text editor for a textfile. The auction system may periodically access the inventory file togather updated data.

Buyer

FIG. 15 is a diagram of one embodiment of a buyer's options, where theuser becomes a buyer for the purposes of purchasing an item—a good orservice—through the online marketplace auction 1500. If the buyer is afirst time user, the buyer can register 1502 with the system and createan account and online profile. If the buyer is a return user, the buyercan log in 1504 to their account. If a buyer is not a returning user,the buyer may be asked to register by creating a username and/orpassword. In one embodiment, the buyer can search 1506 the variousdatabases or online marketplaces for the appropriate auction in which tobuy their good or service. After a buyer has registered and/or logged inand entered a marketplace, a buyer can enter a bid 1508 on an item theywould like to buy. If a buyer has posted a bid and no longer wants towait for an automatic execution of a sale, the buyer can purchase theitem directly from the seller 1510, and/or negotiate directly with theseller 1512 regarding the sale of that item. The buyer can also view allor some of the current orders for this item 1514, as well as view agraphical historical chart 1516 of all or some of the transactions thathave occurred in this market. An order for an item can be either a bidor an offer. A buyer will only be able to place one posted bid on anyindividual item. A buyer can also browse and view all or some of thesellers' offers 1518, as well as browse all or some of the buyers andsellers in the marketplace 1520.

FIG. 16 is an illustration of one embodiment of the continuous dualauction database system's buyer montage 1600. In one embodiment, thebuyer can be directed to a real-time, or substantially real-time,auction database webpage showing the current bids database 1602, themost recent transactions database 1604, the current best bid and offerdatabase 1606, a current offers database 1608, a buyer's toolbox 1610,and/or a graphical chart 1612. In another embodiment, the webpage mayalso include the date and/or time the auction will end 1614. In afurther embodiment, the webpage may include links to additionalinformation, such as news 1616, charts 1618, weather 1620, othermarketplace auctions that are similar to the specific item being sold1622, and/or other marketplace auctions that are similar to the generalitem being sold 1624. In one embodiment of the invention, an auctionsimilar to the specific item can be an item within the same auction; forexample, in the case of a concert, different sections or seats withinthe same event. In another embodiment, an auction similar to thespecific item can be other items related to the same auction; forexample, in the case of a concert, different concert tickets for thesame artist. In one embodiment of the invention, an auction similar tothe general item can be an item not within the same auction; forexample, in the case of a concert, different concert tickets fordifferent artists. Additional links, buttons, information, or othersuitable alternatives may be added or deleted depending on the type ofitem being sold, for example, whether it is a good or service. In oneembodiment, where the item is a service, a link may be included thatwould describe in detail the service and what is included or notincluded, the possibility of modifying the service to include more orless of the services, etc.

In one embodiment, the buyer's toolbox 1610, may allow the buyer variousoptions in which to modify the buyer's bid. One option may allow a buyerto modify the posted bid by a certain dollar amount. In one embodiment,a posted bid, as used herein, is meant to include the lowest amount abuyer desires to buy an item for, which amount is visible to others inthe marketplace. In another embodiment, a posted bid, as used herein, ismeant to include the highest amount a buyer desires to buy an item for,which amount is visible to others in the marketplace. A buyer may havethe option to modify the posted bid at any time by a certain dollaramount by clicking on a button, for example a “Bid+$20” button 1626,wherein the buyer's posted bid amount may be automatically modified bythe amount specified on the button. For example, the button “Bid+$20”may increase the buyer's posted bid by twenty dollars ($20). In oneembodiment of the system, bids can be modified by whole dollar amountseliminating or reducing worthless bid modifications. In one embodiment,the bid can be modified within a certain dollar amount increments, whichincremental amounts may be different based on the item and/or price ofthe item being auctioned. Another advantage of the automatic amountmodification may be to prevent untrue bids. In one definition of anuntrue bid, the buyer enters a bid into the system and ends up notpaying the seller after a transaction either because the buyer (1) neverhad an intention to purchase the item when the bid was placed or (2)developed the intention not to purchase the item after the bid wasplaced. In another definition of an untrue bid, the seller has an itemto sell and wants to artificially inflate the perceived demand for theitem in the current bids database 1602/1702. The seller then places atleast one bid for the item, never intending to actually purchase theitem but rather intending to fool users into thinking that the marketbid rate is higher for the item than it actually is. In anotherembodiment, a bid can be modified in increments of a dollar. In oneembodiment, the amount of the increments may be dependent on the valueof the item in the marketplace. In one embodiment, a bid can be modifiedby using the keyboard or other input device in manipulating the amountof the bid.

In one embodiment, another toolbox 1610 option may be to buy an item atthe current market price listed in the real-time, or substantiallyreal-time, auction database 1602. A buyer wishing to purchase beforetheir posted bid is hit, or otherwise desires to affect a sale quickermay buy at the then-currently lowest posted offer in the marketplace,creating a market sale. A hit, as the term is used herein, is meant toinclude when a seller enters the marketplace by posting an offer ormodifying a previous offer so that the seller's offer equals the buyer'sposted bid. In one embodiment, to execute a market sale, the buyer mayclick on a button, for example a “Buy Mkt” button 1628 in the buyer'stoolbox 1610. In one embodiment, the quantity field 1630 may be expandedand/or may be automatically populated with the quantity of tickets theseller is willing to sell at that price. For example where the item ofinterest is an event ticket, a buyer may not have to purchase alltickets a seller may have available for purchase; however, in someembodiments, they may be required to purchase in a multiple the selleris asking for. The buyer may complete the transaction by clicking on abutton, for example, on the “Submit” or “Continue” button 1632. Afterthe buyer clicks on the button 1632, for example, another dialog box,webpage, or other interface may open to verify that the buyer wishes toproceed with this transaction. This may protect against the buyer frominadvertently affecting a market purchase where the buyer accidentlyclicks on the button 1632. This may also provide the buyer with a chanceto review the information including the item(s) being bought, the price,and the seller before executing the sale. In one embodiment, the item(s)purchased may then be removed from the real-time, or substantiallyreal-time, auction database 1602. The buyer's bid and the seller's offerrelating to this sale may be removed from the real-time, orsubstantially real-time, auction database 1602. In another embodiment,the latest transaction database 1604 may then be updated with the mostrecent sale. In another embodiment, the chart 1612 will update as well,wherein the chart is a graphical representation of the transactiondatabase.

In one embodiment, another option of the toolbox 1610 may be for thebuyer to be able to modify their bid to become the best bid in themarketplace with a single click, as the case may be. In one embodiment,a buyer wishing to modify their bid wherein their bid becomes the newbest bid in the marketplace, the buyer may be able to click on a button,for example a “Best Bid” button 1634, which would automatically modifythe buyer's bid making it the best bid in the marketplace. In oneembodiment, the buyer's bid will be modified by the incremental dollaramount already specified in relation to the specific marketplace. Inanother embodiment, the buyer may be able to indicate by whatincremental dollar amount the buyer would like their new bid to be thebest bid by. In another embodiment, the buyer may be able to enter intothe system the exact price the buyer wants to modify his or her bid to.

In one embodiment, another option available to the buyer in the buyer'stoolbox 1610 may be for the buyer to modify the amount of the item, suchas the amount of tickets or the multiple of tickets the buyer would liketo buy. In one embodiment, the buyer may click on a button, for examplea “Quantity” or “Inc. Qty x#” button 1630, wherein once the buyer clickson the button a dialog box may open, the buyer may be directed to a newwebpage, or the buyer may be presented with another interface, whereinthe buyer can modify the number of items, for example, number of ticketsthe buyer would like to buy. In another embodiment, the buyer may alsobe able to modify the multiple of items, such as tickets the buyer iswilling to purchase.

FIG. 17 is an illustration of another embodiment of the continuous dualauction database system's buyer montage 1700. In one embodiment, thebuyer can be directed to a real-time, or substantially real-time,auction database webpage showing the current bids database 1702, themost recent transactions database 1704, the current best bid and offerdatabase 1706, a current offers database 1708, a buyer's toolbox 1710,and/or a graphical chart 1712. In another embodiment, the webpage mayalso include the date and/or time the auction will end 1714. In afurther embodiment, the webpage may include links to additionalinformation, such as news 1716, charts 1718, weather 1720, othermarketplace auctions that are similar to the specific item being sold1722, and/or other marketplace auctions that are similar to the generalitem being sold 1724. In one embodiment of the invention, an auctionsimilar to the specific item can be an item within the same auction; forexample, in the case of a concert, different sections or seats withinthe same event. In another embodiment, an auction similar to thespecific item can be other items related to the same auction; forexample, in the case of a concert, different concert tickets for thesame artist. In one embodiment of the invention, an auction similar tothe general item can be an item not within the same auction; forexample, in the case of a concert, different concert tickets fordifferent artists. Additional links, buttons, information, or othersuitable alternatives may be added or deleted depending on the type ofitem being sold, for example, whether it is a good or service. In oneembodiment, where the item is a service, a link may be included thatwould describe in detail the service and what is included or notincluded, the possibility of modifying the service to include more orless of the services, etc.

In a further embodiment, the current bids database 1702 may provide thebuyer with additional functionality in modifying their bid. In oneembodiment, the database 1702 may have a column entitled “Multiple”1726, for example, wherein the number of the item being sought is listedin the column. For instance, a buyer may be bidding on an item in whichhe desires a quantity of 10 and wishes to buy them in pairs or otherincrements thus alerting sellers as to what as well as how many of anitem is being bid on. In another embodiment, there may also be a columnentitled “Quantity” (not shown on the figure), wherein the buyer canenter the number of items he has and/or wishes to buy. In anotherembodiment, the column would also include a way for the buyer to modifythe number of items being sought by either clicking on a down arrow typeof a button, for example, or other way in allowing the buyer to easilymodify the number of the item.

In one embodiment, the database 1702 may include a column entitled “BuyNow” 1728, for example. This column may be a button or link wherein ifthe buyer presses or clicks on the “Buy Now” button or link associatedwith the offer the buyer is interested in (these may be in the same row)and a sale may execute. In one embodiment, after the buyer clicks, forexample on the “Buy Now” button, another webpage, dialog box, or otherinterface may open in which the buyer has the chance to review the salebefore completing the transaction. This may also act as a safety toverify the buyer wanted to make this sale and did not accidently clickon the button.

In one embodiment of the invention, when the buyer clicks “Buy Now”1728, the system will allow the buyer to select an offer with themultiple 1726 the buyer wishes to purchase. In another embodiment, theseller may be selling in a larger multiple 1726 than the buyer wishes topurchase; in this case, the buyer has to choose another offer that hasthe multiple 1726 the buyer desires. In another embodiment, if theseller is selling in a larger multiple 1726 than the buyer wishes topurchase, after the buyer clicks “Buy Now” 1728, the system will allowthe buyer to select negotiate 1730 and inquire if the seller is willingto sell the item in the buyer's desired multiple 1726.

In another embodiment, the offers can be sorted by clicking on a “sortsellers by” 1734 down arrow type of a button and selecting criterionsuch as offer price, quantity, multiple, row ranges, aisle seats only,item sold by date, or item color.

In one embodiment, the database 1702 may have a column entitled“Negotiate” 1730, for example. This column may be a button or link wherethe buyer presses or clicks on the “Negotiate” button or link associatedwith the offer the buyer is interested in (these may be in the same row)and a negotiation notification and/or alert may be sent to the intendedseller. In one embodiment, after the buyer clicks, for example, on the“Negotiate” button, another webpage, dialog box, or other interface mayopen in which the buyer may begin negotiations with a seller for thesale of an item. How a negotiation works or may be done is explained inmore detail below with respect to FIG. 21. FIG. 18 is an illustration ofone embodiment of a buyer's item information page 1800. In oneembodiment, where a buyer may initiate the posting of a bid, a dialogbox may open, the buyer may be directed to a new webpage, or the buyermay be presented with another interface where the buyer may be promptedto enter certain information related to the item being sought. Forexample, if the item was an event ticket, such information as the eventname 1802, date 1804, time 1806, venue 1808, section 1810, and/or row1812 may be entered into the system. A buyer may enter all or some ofthis information in any number of ways. For example, a buyer maydirectly type the information into the relevant space, there may be adrop down box in which the buyer can select from, or any other way inwhich to enter data into the system or any combination thereof.

In one embodiment, a link may pull up a map of the venue in which thebuyer may be able to click within a certain section of the venue map andthese entries will be automatically populated with this information.Depending on the item being sought for purchase, a buyer may be requiredto enter some or all of this information, i.e., some of the informationmay be optional. What information a buyer may enter may be dependent onwhat is being sought for purchase by the buyer, wherein additional ordifferent information may be required or optional for the buyer toenter.

The buyer may also input the proxy bid 1814, the posted bid 1816, thequantity of tickets being sought 1818, and in what multiple 1820 thetickets may be bought if the seller has more than one. The proxy bid1814, as used herein, is meant to include the highest amount a buyer iswilling to purchase an item for, which amount is not visible to othersin the marketplace. How a proxy bid 1814 works is explained in moredetail in FIG. 20 below. A buyer may enter this information in anynumber of ways. For example, a buyer may directly type the informationinto the relevant space, there may be a drop down box in which the buyercan select from, or any other way in which to enter data into the systemor any combination thereof. Instead of a separate webpage, this may be apop-up box or other interface. The buyer may click a button, forexample, a “Continue” button 1822, wherein the buyer may choose themeans in which the buyer would like to back the bid. For example, thebuyer may choose to back the bid by using the buyer's system account,which may have been funded by the buyer's own funds, a saved creditcard, or enter a new or different credit card to proceed with theposting of the bid in the marketplace auction.

FIG. 19 is an illustration of one embodiment of a dialog box in which abuyer may select a credit card to use for a transaction 1900. The buyermay select to use the credit card information already stored in thebuyer's account profile, or, if there is more than one credit cardstored, the buyer may choose the credit card they would like to use forthe transaction, or the buyer may enter credit card information into thesystem for the purpose of this transaction. If a buyer has multiplecredit cards on file, at the top of the dialog box, for instance in oneembodiment, the buyer may be able to choose which credit card they wouldlike to use, for example, from a drop down box 1902 or other means. Thebuyer may be required to enter the security code 1904 associated withthe chosen credit card, and/or the buyer's email address 1906, forverification purposes. If the buyer does not have or does not want touse a saved or new credit card, the buyer may choose to use the buyer'ssystem account instead. If the buyer has more than one account, thebuyer may be able to select which account the buyer would like to use toback the bid being posted.

If the buyer would like to use a new and/or different credit card forthe transaction, the buyer may input the type of credit card 1908, thecredit card number 1910, the expiration of the credit card 1912, thesecurity code for the credit card 1914, the first name shown on thecredit card 1916, the middle initial or name shown if shown on the card1918, the last name shown on the credit card 1920, the billing streetaddress 1922, country 1924, city 1926, state 1928, zip code 1930, phonenumber 1932 and/or email address 1934. Some information that a buyer mayinput may be required and some information may be optional. After thebuyer inputs this information, the buyer may click on a button tocontinue, such as a button labeled “Continue,” 1936. The buyer may beasked by the system if the buyer would like to save this credit cardinformation in the system. This may be accomplished in any number ofways, for example in one embodiment a pop-up, dialog box may appearafter a buyer clicks the “Continue” button 1936. If the buyer wishes tosave the credit card, they may be asked to name the card for laterrecognition. If not, in one embodiment or an alternative embodiment, thecredit card information may remain in the system for only the durationof the auction in which the buyer has the bid listed, which bid includesthis particular credit card information. If a buyer does not complete asale by the time the auction ends, the credit card information may bedeleted from the system. In another embodiment, the credit cardinformation may remain in the system as part of the user history.

After the credit card information is entered into the system andconfirmed, and/or the account is verified to contain sufficient funds,the auction database system may upload the item information being soughtfor purchase into the related event-specific real-time, or substantiallyreal-time, auction system database, as noted above with respect to FIG.16. The buyer may be brought into the online auction marketplace and maybe able to see all other bids and offers relating to the specific item.

In one embodiment, a buyer may have the ability to submit multiple bids.For instance, if a buyer is looking to purchase tickets to a certainevent and is open to different sections or levels of a particular venue,the buyer may be able to post several bids across different levels orsections of a particular venue for a particular event. Where some eventlocations, such as stadiums, theatres, etc., are broken down intodifferent “areas,” like sections or levels, a buyer can post a bid basedon the different areas available for each event. In one embodiment,after a buyer posts a bid in an online marketplace, there may be abutton or link such as “Post Bid,” wherein the buyer can then submitanother bid for a different section of the venue. In an alternativeembodiment, after a buyer posts a bid to the online marketplace, adialog box may appear asking whether the buyer would like to postanother bid.

In one embodiment, a buyer may have the ability to submit a single bidfor items across a custom bid group. For instance, if a buyer is lookingto purchase tickets to a certain event and is open to differentsections, levels, rows, or seats of a particular venue, the buyer may beable to post a single bid for all of the tickets that the buyer isinterested in. In one embodiment, after a buyer selects the sections,levels, rows, or seats that the buyer is interested in for a bid group,there may be a button or a link such as “Post Bid,” wherein the buyercan submit a bid for the bid group.

FIG. 25 is an illustration of one embodiment of an interface forentering a bid for an item 2500. In one embodiment, at or about the timewhen a buyer is entering a bid, the buyer may be prompted with a dialogbox or other interface to indicate whether this particular bid should becanceled by a certain date 2502. In further embodiments, the buyer maybe prompted with a dialog box or other interface to indicate whetherthis particular bid should be canceled upon another bid's execution for:(1) the same event 2504; (2) the same event in a particular level 2506;(3) the same event in a particular section 2508; (4) the same event in aparticular row 2510; (5) the same event before a particular date 2512;(6) the same event if the price of the other bid's execution is higherthan a particular price 2514; and/or (7) the same event if the price ofthe other bid's execution is lower than a particular price 2516. If thebuyer indicates he or she would like the bid to be canceled uponexecution of another bid and one of the other bids is executed, thenthis bid may be canceled and removed from the real-time, orsubstantially real-time, auction database system automatically. If thebuyer indicates he or she would like the bid to remain active uponanother bid's execution and one of the other bids is executed, then thisbid may remain active in the real-time, or substantially real-time,auction database system, wherein the buyer can buy additional items,such as event tickets to a specified event. In a further embodiment, thebuyer may be able to post bids in multiple different marketplaces,wherein the buyer may be able to post multiple bids within each suchmarketplace.

FIG. 26 is an illustration of one embodiment of an interface formodifying a bid for an item 2600. In one embodiment, the system mayallow the buyer full functionality to cancel and/or modify bids at anytime. In another embodiment, at or about the time when a buyer isentering modifying a bid, the buyer may be prompted with a dialog box orother interface to indicate whether this particular bid should becanceled by a certain date 2610. In another embodiment, the buyer maymodify the quantity 2602, multiple 2604, price 2606, and/or proxy price2608 for a bid at any time. In further embodiments, the buyer may modifythe bid by indicating that a particular bid should be canceled uponanother bid's execution for: (1) the same event 2612; (2) the same eventin a particular level 2614; (3) the same event in a particular section2616; (4) the same event in a particular row 2618; (5) the same eventbefore a particular date 2620; (6) the same event if the price of theother bid's execution is higher than a particular price 2622; and/or (7)the same event if the price of the other bid's execution is lower than aparticular price 2624.

FIG. 27 is an illustration of one embodiment of an interface showing allactive bids for the buyer 2700. In another embodiment, the user can viewboth their active offers and active bids. In one embodiment, a buyer mayenter as many bids as a buyer wishes; however, as soon as a sale isexecuted all other remaining bids may be automatically canceled from thesystem for that particular item and/or in that particular marketplace.For example, all bids may be canceled upon another bid's execution for:(1) the same event 2702; (2) the same event in a particular level 2704;(3) the same event in a particular section 2706; (4) the same event in aparticular row 2708; (5) the same event before a particular date 2710;(6) the same event if the price of the other bid's execution is higherthan a particular price 2712; and/or (7) the same event if the price ofthe other bid's execution is lower than a particular price 2714. Inanother embodiment, the buyer may cancel all bids within a certain rowor row range 2716, placed before a certain date and time 2718, madebefore another particular bid 2720, made after another particular bid2722 and/or that are aisle seat bids 2724. In another embodiment, thesystem may allow a buyer to keep open remaining bids even after a salehas been completed, wherein the buyer can dictate which bids the buyerwould like to remain active and which bids should be canceled. Inanother embodiment of the invention, a buyer may have multiple bids openbut only want two of the bids linked such that if one bid executes theother linked bid cancels but the remaining bids stay open 2726. Inanother embodiment of the invention, a buyer may have multiple bids openbut only want two or more of the bids linked such that if one bidexecutes the other linked bids cancel but the remaining bids stay open.In another embodiment, the active bids can be sorted via a “view by” box2728. The buyer can sort the active bids by criterion such as ordernumber, item type, event type, quantity, price, levels, sections, rows,whether negotiation is in process, and/or if a bid is linked to anotherbid for cancellation.

In one embodiment, the input of a buyer's credit card information mayfund a guaranty that a buyer will complete a sale by having the fundsavailable to be transferred to the seller. In one embodiment, this maybe of the form in which when a bid is entered or a negotiation started,the buyer's credit card is authorized an amount equal to or greater thanthe amount of the sale price of the item, and optionally any system feesassociated with the transaction. This amount may be placed into anescrow account for a period of time, for example, forty-eight (48) hoursuntil confirmation of the item is received. This time may be modifieddepending on the type of item being sold, the location of the parties,the mode of transferring the item, and the type of parties involved. Ifa buyer does default on a sale, the seller may be credited with anamount greater than the sale price of the item, which sum may beobtained from the escrow account or directly from the buyer's creditcard. Additionally, for example, the defaulting buyer may be bannedand/or reported for fraud. In one embodiment of the invention, after atransaction is executed, the seller is able to use a radio button toindicate if the buyer paid for the item or defaulted on the sale. Inanother embodiment, after a transaction is executed, if the seller doesnot receive payment for his or her item, the seller can contact thewebsite and the website will determine if the buyer has defaulted on thesale. There are many other ways in which the auction system may fund aguaranty for the possibility of a defaulting buyer.

When a buyer is notified of a completed sale, in one embodiment, thebuyer may also be asked how the buyer would like to receive the item.For example, the buyer may be able to select to have the item shipped bymail or otherwise, such as FedEx or UPS, or in the event of e-tickets,for example, email the item directly to the buyer. There are numerousways in which the buyer may select the item from the seller to betransferred to the buyer.

Proxy Offers and Bids:

FIG. 13 is an illustration for assisting in the explanation of how aproxy offer might work, according to one embodiment of the presentdisclosure 1300. One advantage of a seller's proxy offer is that itallows the seller to set up a range value wherein the seller is willingto sell a given item and execute a sale without having to continuouslymonitor the marketplace for new buyers. Another advantage is that theproxy offer may eliminate the need to repeatedly modify the offer. Theproxy offer diagram 1300 may reflect a transaction execution wherein aproxy offer is equal to or less than a posted bid. A proxy offer, asused herein, is meant to include the lowest amount a seller wishes tosell an item for, which amount is not visible to others in themarketplace. For example, seller Y in the diagram 1300 may complete atransaction with buyer A because seller Y's proxy offer is less thanbuyer A's posted bid. In one embodiment where a transaction may match aseller and a buyer together because a proxy offer and a posted bidtransact, the sale may be executed automatically at the posted bidamount. In another embodiment, a seller may be notified of such a liftand have the ability to execute the sale or decline to execute. Inanother embodiment, a sale will only execute due to a posted bid. In oneembodiment, a proxy offer and a proxy bid cannot execute to complete asale as neither one are posted visibly to the entire marketplace. Inanother embodiment, there must be at least one posted order for atransaction—either a posted bid and proxy offer or a proxy bid and aposted offer.

In another embodiment, an email notice or alert could be used to notifya seller that a buyer's posted bid has matched up with a seller's proxyoffer. In another embodiment, the notice or alert may be of the form ofa text message indicating a lift or sale. If a sale is executed or a newbuyer enters a bid that matches a seller's proxy offer, both the bid andoffer may be removed from an auction's real-time, or substantiallyreal-time, auction database and the corresponding auction latesttransaction database may be updated with the sale. There may be othervariants on how a seller's proxy offer may execute a transaction, suchas negotiating, which is explained in more detail below in FIG. 14.

FIG. 20 is an illustration for assisting in the explanation of how aproxy bid might work, according to one embodiment of the presentdisclosure 2000. One advantage of a buyer's proxy bid is that it allowsthe buyer to set up a range value wherein the buyer is willing to buy agiven item and execute a sale without having to continuously monitor themarketplace for new sellers. Another advantage is that the proxy bid mayeliminate the need to repeatedly modify the bid. The proxy bid diagram2000 may reflect a transaction execution wherein a proxy bid is equal toor more than a posted offer. A proxy bid, as used herein, is meant toinclude the highest amount the buyer is willing to pay for a certainitem, which amount is not visible to others in the marketplace. Forexample, buyer C in the diagram 2000 may complete a transaction withseller X because buyer C's proxy bid is more than seller X's postedoffer. In one embodiment where a transaction may match a buyer and aseller together because of a proxy bid and posted offer, the buyer mayor may not decide to execute this transaction. In another embodiment,these types of transaction automatically execute a sale between abuyer's proxy bid and a seller's posted offer. In another embodiment, asale will only execute due to a posted offer. In one embodiment, a proxybid and a proxy offer cannot execute to complete a sale as neither oneis posted visibly to the entire marketplace. In another embodiment,there must be at least one posted order for a transaction either aposted bid and proxy offer or a proxy bid and a posted offer.

In another embodiment, an email notice or alert has been setup to notifybuyer that a seller's posted offer has matched up with a buyer's proxybid. In another embodiment, the notice or alert may be of the form of atext message indicating a hit or sale. If a sale is executed or a newseller enters an offer that matches a buyer's proxy bid, both bid andoffer may be removed from an auction's real-time, or substantiallyreal-time, auction database and the corresponding auction latesttransaction database may be updated with the sale. A sale may also beexecuted where a seller's posted offer and a buyer's posted bid are thesame. There may be other variants on how a buyer's proxy bid may executea transaction, such as negotiating, which is explained in more detailbelow in FIG. 21.

Negotiation:

FIG. 14 is an illustration of one embodiment of a seller's negotiationdialog box 1400. For example, if a seller does not want to execute amarket sale (sell directly to a buyer) because the seller does not likethe then-current market price for the item (or highest posted bid), theseller does not want to wait for their posted offer to be lifted, or forany other reason, the seller may enter into negotiations with a buyer.One purpose of negotiations is to enable the near immediate sale of anitem by allowing a seller to create a mini-marketplace wherein theseller brings in a buyer hoping that the seller and the buyer can reachagreement on the price of the item. The seller may do so by clicking ona negotiate button, for example a “Begin Negotiations” button that maybe in a seller's toolbox, or it may be on the auction system databasewebpage, or some other configuration, like a link or option from a dropdown menu box. If a seller, for instance, clicks on the negotiationbutton, in one embodiment a negotiation dialog box 1400 may appear. Thedialog box 1400 may contain such information as the item beingnegotiated about, the number of the items, the posted offer, when thenegotiation is set to expire, and the new “Price to Offer per Ticket”box. The dialog box 1400 may contain any or all of the foregoing things,some of them, any combination, and/or the addition of other information.In another embodiment, instead of a dialog box, the seller may bedirected to another webpage wherein the seller may invite, or otherwiseselect, the buyer into that new webpage to negotiate the price of theparticular item. In another embodiment, an email may be opened up orcreated wherein the seller may email the selected buyer about theparticular item. In one embodiment, the email may be a notification tolog in and check pending negotiations. In another embodiment, the emailmessage may automatically populate with certain information and be sentby the system on behalf of the seller to the selected buyer to beginnegotiating the amount on a particular item. The selected buyer may thenhave the ability to either accept the offer, refuse the offer, or submita counteroffer to the seller, which may include any new information,such as price, quantity, when the counteroffer expires, etc., or anycombination thereof. The seller may then accept, refuse, or counter thebuyer's counteroffer. In one embodiment, the seller may or may not limitthe number of times the seller and buyer may counteroffer. In oneembodiment, a seller may be alerted by email that a buyer would like tonegotiate with the seller. The seller can then log into the system, goto active negotiations and view the new negotiation. In one embodiment,the seller may be able to respond to the new negotiation through theemail alert.

FIG. 21 is an illustration of one embodiment of a buyer's negotiationdialog box 2100. For example, if a buyer does not want to execute amarket sale (buy directly from a seller) because the buyer does not likethe then-current market price for the item (or lowest posted offer), thebuyer does not want to wait for their posted bid to be hit, or for anyother reason, the buyer may enter into negotiations with a seller. Onepurpose of negotiations is to enable the near immediate sale of an itemby allowing a buyer to create a mini-marketplace wherein the buyerbrings in a seller hoping that the buyer and the seller can reachagreement on the price of the item. The buyer may do so by clicking on anegotiate button, for example a “Begin Negotiations” button that may bein a buyer's toolbox, or it may be on the auction system databasewebpage, or some other configuration, like a link or option from a dropdown menu box. If a buyer, for instance, clicks on the negotiationbutton, in one embodiment a negotiation dialog box 2100 may appear. Thedialog box 2100 may contain such information as the item beingnegotiated about, the number of the items, the posted bid, when thenegotiation is set to expire and the new “Price to Bid per Ticket” box.The dialog box 2100 may contain any of the foregoing things, some ofthem, any combination, and/or the addition of other information. Inanother embodiment, instead of a dialog box, the buyer may be directedto another webpage wherein the buyer may invite, or otherwise select,the seller into that new webpage to negotiate the price of theparticular item. In another embodiment, an email may be opened up orcreated wherein the buyer may email the selected seller about theparticular item. In one embodiment, the email may be a notification tolog in and check pending negotiations. In another embodiment, the emailmessage may automatically populate with certain information and be sentby the system on behalf of the buyer to the selected seller to beginnegotiating the amount on a particular item. The selected seller maythen have the ability to either accept the bid, refuse the bid, orsubmit a counteroffer to the buyer, which may include any newinformation, such as price, quantity, when the counteroffer expires,etc., or any combination thereof. The buyer may then accept, refuse, orcounter the seller's counteroffer. In one embodiment, the buyer may ormay not limit the number of times the seller and buyer may counteroffer.In one embodiment, a buyer may be alerted by email that a seller wouldlike to negotiate with the buyer. The buyer can then log into thesystem, go to active negotiations and view the new negotiation. In oneembodiment, the buyer may be able to respond to the new negotiationthrough the email alert.

Dynamic Bid Groups

FIG. 33 is an illustration of one embodiment of an interface showing avenue categorized by individual seats 3300. In one embodiment, where theuser selects a section as shown in FIG. 31, the groups of rows in thechosen section 3202 may appear. In another embodiment, where the userselects “upper level” as shown in FIG. 30, the groups of rows in thechosen level 3202 may appear. In one embodiment, the section or levelmay be categorized by multiple groups of rows 3204. Further, each groupof rows can contain individual rows 3310, and each individual row cancontain individual seats 3300. In one embodiment, where the user hasselected a group of rows, individual rows may appear. Where the user hasselected an individual row, the individual seats may appear.

In another embodiment, a buyer may choose to define a custom bid groupof event tickets that the buyer is interested in. In such an embodiment,where the buyer selects an event as shown in FIG. 29, the venue map forthe appropriate venue 3002 may appear. The buyer's bid group may haveone or more parameters such as one or more venue levels, one or morevenue sections, one or more venue rows, one or more individual seats, orone or more star levels. The buyer may choose to view all of the offersfor tickets that satisfy the parameters of a particular bid group.

Remote System

FIGS. 35-44 illustrate an application configured to allow management ofthe seller's inventory from a computer system that is remote from theauction system. The remote system could be local to the seller'scomputer, smartphone, tablet, or other computing device. The remotesystem could also be another web server or other internet service remotefrom the auction system. The remote system can support management of theseller's inventory file and act as an editor as describe in FIG. 34.While the example embodiments shown in these figures may use elementssuch as buttons or text dialogs, it is appreciated that any appropriateuser interface elements may be substituted.

FIG. 35 illustrates a login and inventory file selection dialog 3500according to one embodiment. The user is prompted to enter login 3502and password 3504 details as well as the location of an inventory file3506. FIG. 36 is a representation of an inventory file 3600, listingboth buy and sell actions by the user. For each action there is an ordernumber 3602, an item name 3604, an action (buyer or seller) 3606, and anorder price 3608, which are provided by the user. There are also a bestbid 3610 and a best offer 3612 that are updated by the auction system.

FIG. 37 illustrates some of the options that the remote system can allowthe user to configure. In one embodiment, the system can present a userwith a menu 3700 providing options to configure Alerts 3702, LoginCredentials 3704, Startup settings 3706, Profile 3708, and ListingDetails 3710. If the user chooses Alerts 3702 then a submenu 3720 can bedisplayed allowing users to choose which alerts the user wishes toreceive as well as which action should be taken for each alert type.

FIG. 38 illustrates a Listing Details page 3800 displaying theessentially the same listing information in FIG. 36; however, the BestBid price for Order #8 has been updated from $40 to $50. In thisexample, the user is a seller of Order #8 and wishes to sell tickets at$85. Another user who is a buyer has entered a bid of $40 for thetickets, and the auction system has updated the remote system, and thisinformation is presented to the seller. Because the seller has chosen toenable “New Best Bid” alerts, the order listing is highlighted 3810, andalert text “New Bid” 3812 appears on the screen.

FIG. 39 illustrates Listing Details page 3900 displaying the essentiallythe same listing information in FIG. 36, however the Best Offer pricefor Order #63 has been updated from $60 to $58. In this example, theuser is a buyer of Order #63 and wishes to buy tickets for $25. Anotheruser who is a seller has entered an offer of $25 for the tickets, andthe auction system has updated the remote system, and this informationis presented to the buyer. Because the seller has chosen to enable “NewBest Offer” alerts, the order listing is highlighted 3910 and the text“New Offer” 3912 appears on screen.

FIG. 40 illustrates a Listing Details page 4000 displaying theessentially the same listing information in FIG. 36. In this example,the user is a seller of Order #3256 and wishes to sell event tickets for$100. Another user who is a buyer has chosen to enter negotiations withthe user. Because the buyer has chosen to enable “New Offer Negotiation”alerts, the order listing is highlighted 4010 and the text “New BuyNegotiation” 4012 appears on screen. Similarly, FIG. 41 depicts anexample when the user is a buyer of Order #001 and another user who is aseller has chosen to enter negotiations with the user. Because theseller has chosen to enable “New Bid Negotiation” alerts, the orderlisting is highlighted 4110 and the text “New Sell Negotiation” 4112appears on screen.

FIG. 42 illustrates a Listing Details page 4200 where the user hashighlighted an order listing 4210 in order to interact with it in someway. Because the user is a Buyer of this listing, after the user hasselected this order, the user can use the available options to Buy thelisting (at the current Best Offer price) 4212, Negotiate 4214,Counter-Negotiate 4216, Decline Negotiation 4218, Modify the Order 4220,or Cancel the order 4222 This functionality can be substantially thesame as the detailed Buyer functionality described above.

FIG. 43 illustrates a Listing Details page 4300 where the user hashighlighted an order listing 4310 in order to interact with it in someway. Because the user is a Seller of this listing, when the user hasselected an order, the user can use the available options to Sell thelisting (at the current Best Bid price) 4312, Negotiate 4314,Counter-Negotiate 4316, Decline Negotiation 4318, Modify the Order 4320,or Cancel the order 4322. This functionality can be substantially thesame as the detailed Seller functionality described above.

Dynamic Fees:

Another aspect of the marketplace is the dynamic commissions and fees.While event tickets are used in this example, it is known that anyone ofskill in the art could use this marketplace to buy and sell any otherkind of item. When a buyer views an offer from a seller the marketplacewill automatically add any applicable shipping fees. The marketplacetakes into account situations in which a buyer wants to purchase fewertickets than what a seller has available for sale. For example, if theshipping fee for four tickets that a seller has for sale is $20 and abuyer wants to purchase two of the four tickets then the $20 shippingfee is divided amongst the four available tickets, i.e. $5 shipping feeper ticket.

FIG. 44 shows an example of how the marketplace calculates the amount ofmoney a seller would receive for an item. In S4401, a buyer is asked forthe total amount in which they wish to spend for an item that meet theircriteria (the true bid). In S4402, a commission fee is subtracted fromthe true bid. For example, if the marketplace charges a 10% commissionand a buyer's bid is $100 then the marketplace would take a $10commission. In this example the marketplace will display the buyer's bidto the seller as $90, automatically deducting the $10 commission. InS4403, S4404 and S4405, additional shipping or electronic fees aresubtracted. For example, if there is a shipping fee for the tickets thenthe marketplace will automatically deduct the shipping fee. In S4406,the actual amount that a seller would receive from a buyer's true bid isdisplayed to prospective sellers. Continuing the example, if the truebid is $100 and the shipping fee is $5 then the marketplace will displaythe buyer's bid as $85 ($100 bid minus the $10 commission and minus the$10 shipping fee). In equation form the calculation for the amount thata seller would receive from a buyer's bid is:[bid−(bid*commission)]−[(electronic fee) or (shipping fee)].

FIG. 45 shows an example of how the marketplace would calculate theamount of money a buyer would have to pay for an item. In S4501, aseller is asked for the amount in which they wish to receive for theiritem (the true offer). In S4502, a commission fee is added to the trueoffer. For example, if the marketplace charges a 10% commission and abuyer's bid is $100 then the marketplace would add a $10 commission. Inthis example the marketplace will display the buyer's bid to the selleras $110, automatically adding the $10 commission. In S4503, S4504 andS4505, additional shipping or electronic fees are added. For example, ifthere is a shipping fee for the item then the marketplace willautomatically add the shipping fee. In S4506, the actual amount that abuyer would have to pay for the item is displayed to prospective buyers.Continuing the example, if a seller's true offer is $100 is for the itemand the shipping fee is $5 per ticket then the marketplace will displaythe price of the item as $115 ($100 bid plus the $10 commission and the$5 shipping fee). In equation form the calculation for the amount that abuyer would have to pay is: [offer+(offer*commission)]+[(shipping fee)or (electronic fee)].

The marketplace may also include a dynamic incentive program. Forexample a ticket broker may have a large number of tickets available forsale to an event. To encourage ticket brokers to use the marketplace tosell its tickets, the marketplace will give an extra percentage of theprofit after the deduction of the commission. Using the buyer's bid of$100 and the 10% commission from above and an example incentive of 5%,the commission would be $10 making the possible net profit to be $90.The incentive would be 5% of the $90, or $4.50. Thus the seller wouldreceive $94.50 for the one or more tickets purchased by the buyer lessany applicable shipping fees, see the discussion above.

FIG. 46 is an illustration of one embodiment of the continuous dualauction system's audit or parser system. In one embodiment, the user maybe updated in real-time, or substantially real-time, online auctiondatabase system webpage that shows a most recent listed price,transaction price, quantity remaining database 4602. In anotherembodiment, 4603, the webpage may include the old price, new price,quantity of items for user to be alerted of changes and availability oftheir items of interest.

In one embodiment of the invention 4604, users may be updated only withthe quantity available in the market place for the specific items ofinterest. In one embodiment, 4605, alerts go out for new listingavailable in the market place and yet another embodiment shows deleteditems from the market place, 4606.

Dynamic Events

Another aspect of the marketplace is the dynamic bids across dynamicevents for custom dates. While event tickets are used in this example,it is known that anyone of skill in the art could use this marketplaceto buy and sell any other kind of item. For instance, if a buyer islooking to purchase tickets for any musical event taking place in city Xduring the last week of April, the buyer may customize his bid to selectfrom one or musical events, for several different seats, taking placeduring that custom time frame in his selected city. Once the buyer's bidis accepted by a seller to one event on one date the transaction isfinalized. Once the transaction is completed the buyer may instruct thesystem to cancel all remaining bids for the other several differentseats to several different events that occurs on several different datesupon the buyer's wish to cancel his bid.

An example of the dynamic event may be bidding for one or more EltonJohn concerts in Vegas for the month of April; it may be one or more popconcerts held in New York City during the holiday season. A seller mayaccept the buyer's offer for Elton John concert for 28 Apr., 2016, rowfive, seats six through sixteen. Once the transaction is completedbetween the buyer and the seller, the remaining bids may stay active orbe dropped depending on the option the buyer chooses in his initial bid.
